Vehicle Systems Disassembly & Assembly
Mast Adjustment Lower Bearings
(A) Zero clearance. (B) Minimum clearance. (C) Zero clearance.
(3) Bearing. (4) Bearing. (5) Shims. (6) Shims.
16. Make sure whether inner mast lower bearings
are properly shimmed in the intermediate mast
by rolling up and down and moving inner mast to
right and left. If clearance between both masts
can be detected, pull down the inner mast from
the bottom of intermediate mast. Inner lower
bearings can be easily extruded. Add shim 0.5
mm or 1 mm to both inner lower bearings. If
inner mast is stuck and do not move rolling up
and down, there might be excessive shim. Pull
out the inner mast from the intermediate mast
and remove shim 0.5 mm to both inner lower
bearings. Repeat same procedure of aboves until
properly shimmed. There is to be contact zero
clearance (C) between inner lower bearings and
intermediate channel at narrowest point.
E. Upper Bearing Adjustment of
intermediate Mast
Follow same procedure with above B.
F. Upper Pad Adjustment of Intermediate
Mast
Follow same procedure with above C.
17. If the seals and bearings were removed from the
mast mounting blocks, install new ones.
18. Put a small amount of clean grease on mounting
pins (11). Install mounting pins (11) into mast
mounting blocks.
